Convertibles use a 1-piece panel to reinforce the floor & minimize chassis flex. This version has been engineered to adapt that same technology to coupes & fastbacks.

This is a raised platform where the front seats mount. It runs from the driver side frame rail, over the transmission tunnel to the passenger side frame rail. It must be welded into place. Center consoles should be notched to fit over the panel, just like in convertibles. 1965-1968 cars can use this panel to lower the seats for additional headroom.
